Detailed Description of the Invention (Industrial Field of Application) The present invention is a portable yarn tester set, specifically, it can be used to check the approximate quality of yarn such as the thickness of spun yarn (1), strength (1), number of twists (1) unevenness, etc. The present invention relates to a portable thread tester set that is convenient for carrying out measurements.

(Conventional technology) Prior to shipping, various types of yarn manufactured in a spinning factory are linked in small quantities for each type. The yarn count), single yarn strength, number of twists, yarn unevenness, etc. are inspected.

(Problem to be solved by the invention) The spun yarn shipped as described above is sample 7,
(Although strict checks are being conducted on f'l,
Many factories at shipping destinations (users) do not have testing equipment to confirm the quality of the yarn, so when you have doubts about the yarn you have purchased, find a defective part in some yarn, or, for example, 2. If a situation arises such as when the tension is not correct, please contact the supplier (manufacturer) of the yarn.
Currently, the manufacturer dispatches a supervisor to listen to the points pointed out by the user, and then takes some of the threads in question back to the company for re-inspection. As a result, manufacturers are required to spend a lot of unexpected time and effort, and users are unable to check the quality of the yarn with their own eyes, which is inconvenient for SouH.

The present invention provides a portable yarn tester set that allows the user to measure and confirm the approximate quality of yarn.

(Means for Solving the Problems) A portable thread tester set according to the present invention has an ill length tester set of 1
